The purpose of this document is to summarize the best scientific information presently available for bull trout (Salvelimus confluentus) throughout Oregon and to review their historical and current status. What started out as a relatively simple exercise to review and update the status report by Ratliff and Howell (1992) based...

Two broiler feeding experiments were carried out to determine the feeding value of Pacific Northwest-grown soybeans. In both experiments, solvent soybean meal (SBM) protein, when replaced one to one with extruded soybean (ESB) protein, produced no significant effects on body weight, feed conversion and mortality. Protein from raw soybean (RSB)...
The objective of this thesis is to provide a predictive model for the archaeological investigation of the first farmsteads in the Pacific Northwest, established in the early- and mid-nineteenth century by Canadien and Métis families retiring from their service in the fur trade. Past studies of this population have either...
The study of the infra-specific ranks (i.e., subspecies and variety) can be considered
the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker
(Fabaceae) is the most taxon rich species in the U.S. flora currently including 40
taxonomic varieties. These varieties were described using traditional taxonomic
methods primarily...
Herbs have been used for many centuries in diverse civilizations for the treatment of heart disease. Only a few natural supplements claim to have direct cardiovascular actions including hawthorn (Crataegus spp.) and berberine derived from the Berberidaceae family. Several different studies indicate important cardiovascular effects of hawthorn and berberine. For...
An interlaboratory study of Mg/Ca and Sr/Ca ratios in three commercially available carbonate reference
materials (BAM RS3, CMSI 1767, and ECRM 752-1) was performed with the participation of
25 laboratories that determine foraminiferal Mg/Ca ratios worldwide. These reference materials containing
Mg/Ca in the range of foraminiferal calcite (0.8 mmol/mol to...
Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...
